A concrete pavement with a large volume (15% to 35%) of interconnected voids was specified on a project for the parking lot that takes in storm water at a rapid rate of 3 to 5 gallons per minute per square foot of surface area. This concrete material is considered:
  1. Pervious
  2. Impervious
  3. Impermeable
  4. Cellular foam
Explanation
Answer - A - A concrete material that is pervious in character is a concrete pavement with large volume of interconnected voids. Pervious material captures storm water and allows it to seep into the ground, reducing storm water runoff. An impervious material/surface prevents storm water from infiltrating into the ground and as a result increases runoff, reduces groundwater recharge, and degrades surface water quality.
